ELECTROMAGNETIC LIGHT BATHING APPARATUS.

Application filed August 25. 1924, Serial No. 733,992, and in GermanyMarch 13, 1924.

It has become known to make magnetic forces act upon the human body insimultaneously applying heat in order to prevent or heal diseases. Theadvantages deriving from the treatment with differently coloured lightrays are also known.

This invention has for its object to utilize as intensively as possiblethe well known physical effects upon the human body and it utilizes forthis purpose a light heating apparatus which is capable to discharge atthe same time magnetic forces.

According to the invention an electromagnet is inserted in anincandescent lamp arranged in a cage between the holder or base of thelamp and the incandescent body; the coil of the electromagnet beingseries-connected. According to the invention the socket which enclosesthe magnet is made from metal and the cage which is directly mounted onthe screw cap or base of the lamp is made from soft iron. The inventioncan be carried out in different manners and the only figure of theaccompanying drawr ing shows by way of example the preferred form ofconstruction in elevation, partly in section,

A lamp holder (Z of metal is fixed on the end of a flexible cord 7) theother end of which is attached to a plug a adapted for connection with asource of alternating current, for example, alternating current from anordinary 110-volt light circuit. In the flexible cord 7) a switch 0 ispreferably inserted. On the lamp base 0 a high metal ring f is screwedthe current-leading threaded part of which is of such. a length that aglow lamp 9 screwed into the holder leaves a gap it between said base aand the central contact as well as the central lamp contact is. In thisgap h an electromagnet Z is in serted which consists of a coil m inwhich an iron core a is located. The electro-n1agnet Z is limited atboth ends by insulating pieces 0. The contact plates 79 above saidinsulating pieces 0 are fixed on the coil we so that they are insulatedfrom the core. The ends of the coil wire are connected with said contactplates 77. The coil m connects therefore the base 6 with the centralcontact is of the lamp so that the current for the lamp must flowthrough the coil.

A cage 9 of soft iron is mounted on the base 6 of the lamp holder. Thiscage encloses the lamp and is open at the upper end so that the lampbulbs can be easily exchanged and differently coloured glow lamps may bescrewed in. The effect of this arrangement is as follows:

The heat waves expand the parts of the human body on which the lightrays are directed and the light waves act at the same time, giving thebeneficial effects of a direct heat treatment, as well as thestimulating effects upon the tissues of colored light rays. Owing to theelectromagnet inserted in the metal casing electric excitations areproduced in this metal casing which propagate in the casing and createaround the same an electro-magnet field in which the diseased part ofthe human body is located.

By this means as the electro-magnet and its casing and the soft ironwire cage serve as the elements of a transformer and condenser (with airas a dialectic between), eddy currents (Foucault currents) are set up byinduction, which currents apparently have the effect of promoting thetransference of radiant heat to the tissues by diathermic action, which,according to Joule, Foucault, dArsonval, Kowarschik and others causetissue stimulation, aiding nature in the alleviation or cure of disease.

The holder which laterally encloses the magnet is made from metal onpurpose in order to favour the production of Foucault currents acting onthe human body, the cage of larger diameter being made on purpose fromsoft iron in order that by the wires of the same the dispersed lines offorces of the magnet are deflected so far they do not serve for theFoucault excitation and form small poles by magnetic induction which actalso upon the light waves.

The magnetic forces produce in the treated part of the human bodycorresponding electric conditions. According to the searches made byProfessor Finsen differently coloured lamps and consequently diiferentlycoloured light rays are used according to the kind of disease. Thisapparatus permits therefore simultaneously an electro-magnetictreatment, a treatment by light rays and a strong heating of thediseased organ.

I claim In a. device of the character set forth, in combination, aholder, a base, mounted in the holder and having a center contact, alamp socket mounted in the holder in spaced relation to the base, anincandescent lamp mounted in the free end of said socket and having acenter contact, an clecl'i'oinegnet, comprising =1 wire coil and an ironcore mounted Within said socket in the space between said base and saidglow lamp, said coil having end contacts engaging the center contacts ofthe base and lzunp and electrically connecting said coil and lamp inseries, a. soft iron cage spzicedly surrounding said socket and saidlamp, and means for connecting the device 10 to a source of alternatingelectric current.

In testimony whereof I affix my signature.
